CoQ10 Explained: Ubiquinone vs. Ubiquinol, How Much, and When to Take It
CoQ10 is one of the best-known supplements in the US, especially among adults over 40. At the same time, the labels can be confusing: ubiquinone, ubiquinol, 100 mg, 200 mg, softgels, capsules. This guide explains what CoQ10 actually is, what the two forms mean, and what to compare before you buy.
What Is CoQ10?
Coenzyme Q10, short CoQ10, is a compound your body makes on its own. It is found in nearly every cell, especially in the mitochondria, the small structures often called the "power plants" of the cell. There, CoQ10 takes part in the process that turns the food you eat into usable cellular energy. CoQ10 also works as an antioxidant.
Organs with high energy needs, like the heart, liver and muscles, contain the most CoQ10. The name "ubiquinone" comes from the word ubiquitous, meaning "found everywhere", because it really is in almost every cell.
Why Do People Take It?
Your body makes CoQ10 itself, so why supplement it? A few reasons people commonly mention:
- The body's own CoQ10 levels decline with age.
- Food provides only small amounts. Organ meats, fatty fish and beef are among the richer sources, but even they contain just a few milligrams per serving.
- Some people simply want a steady, measured daily amount.
Important: if you take any prescription medication, talk to your doctor before starting CoQ10. This is especially true for blood thinners and blood pressure medication, and anyone taking statins should discuss it with their doctor as well.
Ubiquinone vs. Ubiquinol
CoQ10 comes in two forms, and you will see both names on labels:
- Ubiquinone is the oxidized form. It is the classic, most widely studied form of CoQ10, very stable, and the most common form in supplements.
- Ubiquinol is the reduced form. The body naturally converts between the two forms all the time.
Ubiquinol is usually more expensive and less stable, so it is often sold in special softgels. Ubiquinone is stable, affordable and has decades of use behind it. For most people the more important question is not which form, but whether they take it consistently every day, with food.
How Much CoQ10?
Supplements usually contain between 100 mg and 300 mg per serving, with 100 mg and 200 mg being the most common. When you compare products, look at:
- The mg per capsule, not just the number of capsules in the bottle
- How many capsules make one serving
- The price per 100 mg, which is the fairest way to compare
A bottle of 30 capsules at 200 mg each gives you 6,000 mg in total. A bottle of 60 capsules at 50 mg each gives you only 3,000 mg, even though it has twice as many capsules.
Take It With Food
CoQ10 is fat-soluble. That means it dissolves in fat, not in water. The practical tip: take it with or shortly before a meal that contains some fat, for example breakfast with eggs, yogurt or nuts, or dinner. Taking it on an empty stomach with just water is the least ideal option.
Capsule or Softgel?
Both work. Softgels contain CoQ10 dissolved in oil and are usually made with gelatin. Capsules contain CoQ10 powder and can be made from plant-based hypromellose, which makes them suitable for vegetarians. If you take a powder capsule, simply take it with a meal that contains some fat.
Checklist Before You Buy

- Is it a single ingredient, or mixed into a blend with unclear amounts?
- Is the capsule vegetarian, if that matters to you?
- Is it made in a GMP or NSF-registered facility?
- What is the price per 100 mg?
